PSDs are used in applications ranging from human eye movement monitoring and 3-D modeling of human motion to laser, light source, and mirror alignment. They are also widely used in ultra-fast, accurate autofocusing schemes for various optical systems, such as microscopes, machine tool alignment, and vibration analysis. PSDs can obtain the position of a beam within fractions of microns. They are divided into two families: segmented PSDs and lateral effect PSDs
